DETAILED DESCRIPTION
[0021] In order to more clearly describe the object, technical
solution and advantages of the disclosure, the disclosure will be
described in detail in conjunction with the accompanying drawings.
Obviously, the embodiments herein are only part of the embodiments
of the disclosure. All other embodiments obtained by those ordinary
skilled in the art based on the embodiments of the disclosure
without any creative efforts fall into the protection scope of the
disclosure.
[0022] The shapes and sizes of the components in the drawings do
not reflect the true proportions, and the purpose is merely to
illustrate the contents of the disclosure.
[0023] An embodiment of the disclosure provides an array substrate,
as shown in FIG. 1, which includes: a base substrate (not shown in
FIG. 1); and a plurality of data lines (not shown in FIG. 1) and a
plurality of dummy leads 3, the plurality of data lines and the
plurality of dummy leads 3 are located in the same layer on the
base substrate, and the plurality of data lines and the plurality
of dummy leads 3 extend in the first direction Y; and at least one
of the dummy leads 3 includes a plurality of conducting wires 4,
the plurality conducting wires 4 extend in the first direction Y
and are disconnected with one another.
[0024] In the array substrate in accordance with the embodiment of
the disclosure, due to the case that the data line and the dummy
lead are relatively close, such as the case that both the data line
and the dummy lead are located at the same pixel gap, the data line
and the dummy lead are easy to be short-circuited. Compared with
arranging one whole dummy lead, since the dummy lead includes a
plurality of conducting wires which extend along the first
direction and are disconnected with one another, when the dummy
lead and the data line in the same layer are short-circuited, the
length of the conducting wire short-circuited with the data line is
reduced, and the voltage reduction degree of the data line is
reduced, so that the dark lines are avoided, the display effect and
the user experience are improved.
[0025] In a specific implementation, the plurality of data lines
and the plurality dummy leads extend along the first direction Y.
The arrangement of the plurality of data lines and the plurality of
dummy leads in the second direction X can be determined according
to actual needs, wherein the second direction X and the first
direction Y can be cross-arranged, for example, vertically crossed
or crossed with another angle, and is not limited herein.
[0026] Optionally, in the array substrate in accordance with the
embodiment of the disclosure, as shown in FIG. 1, different
conducting wires 4 in each dummy lead 3 are on the same straight
line extending along the first direction Y, so that the dummy leads
uniformly arranged in the area where the array substrate is
located, and the uniformity of product display can be further
guaranteed.
[0027] Optionally, as shown in FIG. 1, the lengths of different
conducting wires 4 are equal. Thus, the same voltage reduction
degree can be guaranteed for the data lines. In the embodiments of
the disclosure, all conducting wires 4 on the array substrate can
be arranged to the same length. In addition, the lengths of
conducting wires 4 can be arranged regionally, for example, each
conducting wire 4 belonging to the same dummy lead 3 has the same
length, or the conducting wires 4 in the middle of the display area
have the same length, the conducting wires 4 at the edge of the
display area have the same length. The lengths of the conducting
wires can be arranged according to actual needs, and is not limited
herein.
[0028] Optionally, the array substrate in accordance with the
embodiment of the disclosure, as shown in FIG. 1, may further
include a plurality of touch electrodes 5 located on the base
substrate and in a different layer with the data lines.
[0029] The plurality of touch electrodes 5 are arranged in an
array, and the plurality of touch electrodes 5 include a plurality
of touch electrode columns 6, the column direction of the touch
electrode columns is the first direction Y, and the number of
conducting wires 4 in each dummy lead 3 is equal to the number of
touch electrodes 5 in a touch electrode column 6. In this way, it
is easy to design the structure of the array substrate and to
realize the process of forming a plurality of conducting wire
segments.
[0030] In the array substrate in accordance with the embodiment of
the disclosure, as shown in FIG. 1, the number of conducting wires
4 in each dummy lead 3 is equal to the number of touch electrodes 5
in a touch electrode column 6, so as to facilitate the structure
design of the array substrate and easily realize the process of
forming a plurality of conducting wire segments. On this basis, the
lengths of different conducting wires 4 in each dummy lead 3 are
equal. Thus, the length of each conducting wire can be guaranteed
to be the shortest, and the voltage reduction degree of the data
line can be reduced to the greatest extent.
[0031] Optionally, in the plane where the array substrate is
located, the orthographic projection of each touch electrode column
on the base substrate has an overlapping area with the orthographic
projection of at least one dummy lead on the base substrate, so
that each touch electrode column corresponds to at least one dummy
lead, to enable the dummy leads to be distributed substantially
uniformly on the base substrate.
[0032] Optionally, in the array substrate in accordance with the
embodiment of the disclosure, as shown in FIG. 1, the orthographic
projection of the interval area between the two adjacent conducting
wires 4 in each dummy lead 3 on the base substrate falls into the
orthographic projection of the interval area between the two
adjacent touch electrodes 5 in each touch electrode column 6 on the
base substrate. That is, each touch electrode corresponds to at
least one conducting wire, so that the position of the conducting
wire corresponds to the position of the touch electrode, making the
arrangement of the conducting wires more uniform, and further
improving the display uniformity.
[0033] Optionally, the array substrate in accordance with the
embodiment of the disclosure may further include a plurality of
touch leads which extend in the first direction and are arranged in
the second direction, and a plurality of pixels arranged in an
array on the base substrate; each touch electrode is connected with
at least one touch lead; the plurality of pixel units include a
plurality of pixel unit columns, the column direction of the
plurality of pixel unit columns is the first direction; the sum of
the number of dummy leads and the number of touch leads is equal to
the number of pixel unit columns.
[0034] As shown in FIG. 1, the array substrate includes touch leads
2 connected with touch electrodes 5, and a drive circuit 7
connected with the touch leads 2 and the dummy leads 3. The drive
circuit 7 provides common voltage signal and touch signal to the
touch leads 2. In addition, the drive circuit 7 can also provide a
common voltage signal to the dummy leads 3 to enhance the display
uniformity. The touch lead 2 is electrically connected with the
touch electrode 5 at connection area A. Specifically, the touch
lead 2 is electrically connected with the touch electrode 5 through
a via hole at the position of the connection area A. FIG. 1
illustrates that each touch lead and the touch electrode are
electrically connected through two connecting areas A. In a
specific implementation, the touch lead and the touch electrode can
be electrically connected through only one connecting area or more
connecting areas, the disclosure will not be limited thereto. FIG.
2 is a schematic diagram of the relation between part of the pixels
and the leads. In FIG. 2, each pixel 8 includes three sub-pixels 9.
For example, each pixel 5 may include a red sub-pixel, a blue
sub-pixel and a green sub-pixel, or more sub-pixels, and is not
limited herein. Each sub-pixel is defined by intersected gate line
L1 and data line L2. Each sub-pixel unit 9 includes a Thin Film
Transistor (TFT) 10 connected with the gate line L1 and data line
L2 and a pixel electrode 11 connected with the TFT. Each pixel
column of the pixels 8 corresponds to a dummy lead 3 or a touch
lead 2, which can ensure that the number of leads (touch leads or
dummy leads) is equal to the number of pixel columns, thus ensuring
the display uniformity of the product. In addition, when the
different conducting wires in each dummy lead do not align in the
first direction, the leads can be uniformly arranged in the area
where the array substrate is located, and the display uniformity of
the product can be further guaranteed.
[0035] In a specific implementation, each touch electrode column
corresponds to N pixel columns, and each touch electrode column
includes M touch electrodes. As shown in FIG. 1, each touch
electrode column 6 needs to correspond to M touch leads 2. When
M<N and each touch electrode is connected with one touch lead,
in order to ensure the uniformity of display, that is to say, in
order to ensure that the number of pixel columns is the same as the
number of leads, N-M dummy leads are needed in the coverage area of
each touch electrode column. FIG. 1 merely illustrates that the
orthographic projection of each touch electrode column covers the
orthographic projection of one dummy lead. In the actual design of
the array substrate structure, in order to ensure the uniformity of
display, it is necessary to determine how many dummy leads each
touch electrode column corresponds to according to the M, N and the
number of leads connected with each touch electrode. In addition,
the touch electrodes in FIG. 1 are rectangular, and the touch
electrodes can be of other shapes. The shape of the touch
electrodes and the lead arrangements of the array substrate can be
selected according to actual needs.
[0036] Optionally, in the array substrate in the embodiments of the
disclosure, the touch lead includes a first sub-touch lead and a
second sub-touch lead located in different layers and connected
through via hole; the second sub-touch lead is arranged in the same
layer as the data line.
[0037] That is, the dummy lead and the second sub-touch lead are
arranged in the same layer, and the orthographic projection of the
first sub-touch electrode on the base substrate has an overlapping
area with the orthographic projection of the second sub-touch
electrode on the base substrate. Therefore, the first sub-touch
electrode and the second sub-touch electrode located on different
layers can be connected through via hole, so that the resistance of
the touch lead can be reduced. Arranging the second sub-touch lead
and the data line in the same layer can simplify the manufacturing
process of the array substrate.
[0038] Next, by taking the sectional views along AA' and BB' in
FIG. 2 as an example, the structure of the array substrate in
accordance with the embodiments of the disclosure is illustrated.
FIG. 3 is a sectional view along AA' in FIG. 2, and FIG. 4 is a
sectional view along BB' in FIG. 2. As shown in FIG. 3, the upper
array substrate includes: a base substrate 12, a gate electrode 13,
a gate insulating layer 14, an active layer 15, a source electrode
16, a drain electrode 17, a pixel electrode 11 connected with the
drain electrode 17, a data line 18 and a second sub-touch lead 19
arranged in the same layer as the source electrode 16 and drain
electrode 17, a first insulating layer 20, a first sub-touch lead
22 connected with the second sub-touch lead 19 through a via hole
21 arranged in the first insulating layer 20, a second insulating
layer 23, and a touch electrode 5 connected with the first
sub-touch lead 22 through the via hole 21 arranged in the second
insulating layer 23, wherein the second sub-touch lead 19 can be
called SDT (Source Data Metal) line, the first sub-touch lead 22
can be called TPM (Touch Panel Metal) line, and the dummy lead
arranged in the same layer as the SDT line in the embodiments of
the disclosure can be called dummy SDT line.
[0039] In addition, the array substrate in accordance with the
embodiments of the disclosure, as shown in FIGS. 3 and 4, may
further include touch dummy leads 24 located on the base substrate
12 and in the same layer as the first sub-touch leads 22; the
orthographic projection of the touch dummy lead 24 on base
substrate 12 has an overlapping area with the orthographic
projection of the dummy lead 3 on base substrate 12; the touch
dummy lead includes a plurality sub-leads which extend in the first
direction Y and are disconnected with one another (not shown in the
figure).
[0040] The touch dummy lead can be represented as a dummy TPM line,
and the touch dummy lead can also be arranged as a plurality of
sub-leads which extend along the first direction and are
disconnected with one another, so that the arrangement of the touch
dummy lead is consistent with that of the dummy lead, which is
conducive to the uniformity of arrangement, thus facilitating the
display uniformity. The arrangement of the sub-leads in the touch
dummy lead can refer to that of each conducting wire in the dummy
lead, and no more discussion will be repeated here. Similar to FIG.
3, the array substrate shown in FIG. 4 includes: a base substrate
12, a gate electrode 13, a gate insulating layer 14, an active
layer 15, a source electrode 16, a drain electrode 17, a pixel

and a dummy lead 3 arranged in the same layer as the source
electrode 16 and drain electrode 17, a first insulating layer 20, a
touch dummy lead 24, a second insulating layer 23, and a touch
electrode 5.
[0041] Based on the same invention concept, the embodiments of the
disclosure provide a display panel, including the array substrate
in accordance with the embodiments of the disclosure. The display
panel in accordance with the embodiments of the disclosure may be,
for example, a Touch and Display Driver Integration (TDDI) type
display panel, a liquid crystal display panel, or an organic light
emitting diode display panel. Since the principle of solving
problems of the display panel is similar to that of the array
substrate, the implementation of the display panel can be referred
to that of the array substrate, and there will be no
repetition.
[0042] Based on the same invention concept, the embodiments of the
disclosure provide a display device, including a display panel in
accordance with the embodiments of the disclosure.
[0043] The display device in accordance with the embodiment of the
disclosure may be, for example, a device such as a mobile phone, a
tablet computer, etc.
[0044] Since the principle of solving problems of the display
device is similar to that of the display panel, the implementation
of the display device can be referred to that of the display panel,
and there will be no repetition.
[0045] Based on the same inventive concept, the embodiments of the
disclosure also provide a method for manufacturing the array
substrate. Since the principle of solving problems of the method is
similar to that of the array substrate, the implementation of the
manufacturing method can be referred to that of the array
substrate, and there will be no repetition.
[0046] The method includes the step of forming a pattern of dummy
leads and a pattern of data lines in the same layer on the base
substrate; wherein the forming of the pattern of the dummy leads
includes forming a pattern of a plurality of conducting wires which
extend in the first direction and are disconnected with one another
via a mask including a plurality of openings which extend in the
first direction and are disconnected with one another.
[0047] Next, an example is given to illustrate the mask used in the
method for manufacturing the array substrate in accordance with the
embodiments of the disclosure. As shown in FIG. 5, the mask 25
includes a plurality of openings 26 which extend in the first
direction Y and are disconnected with one another, and some
openings are aligned in the first direction, such as a plurality of
openings in the area 27 are aligned in the first direction Y. By
evaporating metal materials with the mask, a plurality of aligned
and disconnected conducting wires along the first direction can be
formed in the corresponding part of the area 27 on the base
substrate to form a dummy lead. Specifically, for example, a touch
lead pattern and a data line pattern can be formed on the base
substrate, and after that a dummy lead pattern can be formed by
using the mask as shown in FIG. 5.
[0048] In summary, in the array substrate, method for manufacturing
the same, display panel and display device in accordance with the
embodiments of the disclosure, since the dummy lead includes a
plurality of conducting wires which extend in the first direction
and are disconnected with one another, when the dummy lead and the
data line located in the same layer are short-circuited, the length
of the conducting wire short-circuited with the data line is
reduced, and the voltage reduction degree of the data line is
decreased, so that the dark lines are avoided, the display effect
and the user experience are improved. In specific implementation,
the number of conducting wires in each dummy lead can be arranged
to be equal to the number of touch electrodes in a touch electrode
column, so as to facilitate the structure design of the array
substrate and easily realize the process of forming a plurality of
conducting wire segments. On this basis, the lengths of different
conducting wires in each dummy lead are equal. Thus, the length of
each conducting wire can be guaranteed to be the shortest, and the
voltage reduction of the data line can be avoided to the greatest
extent. Specifically, the sum of the number of dummy leads and the
number of touch leads can be arranged to be equal to the number of
pixel unit columns, thus the display uniformity of the products can
be assured. In addition, when different conducting wires in each
dummy lead are aligned in the first direction, the lead can be
uniformly arranged in the area where the array substrate is
located, and the display uniformity of the product can be further
guaranteed.
